[NTG-context] trying to delete an attribute reference of a non attribute node

Hi! The following example throws the error: ! error: (nodes): trying to delete an attribute reference of a non attribute node mtx-context | fatal error: return code: 1 \setbreakpoints [compound] \useMPlibrary [dum] \starttext \startTABLE \NC \externalfigure [foo-bar] [width=\textwidth] \NC foo bar foo bar foobarfoobar \bold{aaaaaaaaaaaa} \NC\NR \stopTABLE \stoptext Sorry for the not so minimal example. In the actual text I'm not using the `dum` library, I'm including actual graphics. So I don't believe that's the issue. It might have something to do with word breaking, that's my gut feeling. What is the issue here? ConTeXt ver: 2016.06.26 19:00 Marco
